Abstract
A 23-year-old woman presented with neck, back, and left arm pain with left shoulder weakness. Her medical history was unremarkable for cervical trauma. Neurologic examination showed hypoesthesia and hypoalgesia in the C5–C8 dermatomes, with hypoactivity of deep tendon reflexes at the left upper extremity. Magnetic resonance imaging revealed scoliosis associated with an intradural left anterolateral arachnoid cyst at the C3–T1 levels, compressing the spinal cord, scalloping the posterior surfaces of vertebral bodies, and expanding the left neural foramina (Fig. 1). There was fatty atrophy of the left shoulder muscles due to brachial plexopathy (Fig. 2). Fig. 2Coronal fat-saturated T2-weighted (Left) and coronal T1-weighted (Right) magnetic resonance images of cervicothoracic spine revealed scoliosis and fatty atrophy of the left shoulder muscles due to brachial plexopathy (arrows).
